Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages If I either: a) Change the order of Talkers so that a different Talker is at the top of the list, or b) Change the details of the top talker (eg. change the Voice or Speed of an eSpeak voice), then the change has no effect on subsequent speech, although the change is shown in KTTSMgr, and HOME/.kde/share/config/kttsdrc appears to be updated as expected. If I log-out (Leave -> Logout, end of session) and then log-in again as the same user, then the change is recognized.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug.
